SparkFun GPS-RTK - ZED-F9R Flashed new firmware lost GPS data

Product(s) do not work as advertised per our hook-up guide or other documentation on the SparkFun website product page

So far…

  • Spent number of days looking at documents between sparkfun and u-blox / u-center to get 2 new RTK GPS working

  • both ZED-F9R powered on and gave data in u-center

  • 1st problem followed guides for rover and base and config would not save (yes I found others with same problem and tried same fix with no luck)

  • 2nd problem following guides for firmware, updated one of the units and now it looks like its saves configs but NO GPS DATA basically useless now…

I could use some help trying to get the board back to just a running state.

Have you tried the steps here https://learn.sparkfun.com/tutorials/ho … s-receiver and here? https://learn.sparkfun.com/tutorials/sp … -guide/all

Are the units’ LEDs lighting up @ power?
